Abrégé
Systems(100) and methods for depositing a thin film layer onto a flexible ferromagnetic substrate (120) include a porous block (140) in a deposition zone(130) and a plurality of magnets(170) embedded within the porous block(140). The magnets(170) provide a downward force on a flexible ferromagnetic substrate(120) being transported over the porous block(140), e.g., in a reel-to-reel system(100). Pressurized gas is forced upward through the porous block(140), providing an upward force that balances the downward force and supports the substrate at a desired height above the porous block(140). The substrate(120) is thus held flat during transport through the deposition zone(130), enabling uniform deposition of a thin film layer.

Thin film PV cells and strings of such cells that may be electrically joined with conductive tabs or ribbons. A semi-flexible, electrically conductive adhesive is applied to join the tabs to the front and back of a cell, providing a conductive pathway between the tab and solar cell, with good adhesion to both. The tabs may be constructed of one or more materials having a thermal expansion coefficient that closely matches that of the substrate material of the cells, so that when the string or module is subsequently heated, mechanical stress between the tab and solar cell is minimized. The semi-flexible nature of the ECA also acts to relieve stress between the tab and the solar cell, decreasing the possibility of adhesion failure at critical locations. One or more dielectric materials may be applied to the PV cells and/or the tabs in regions where a tab crosses the edge of a cell, to avoid electrical shorting between the negative and positive electrodes of the cell.
